' Application led. April 29, 1907. Serial No. 370,823.

To all whom it may concern:

` Be it known that I, AXEL ENGLUND, a citizen of Finland, residin at Mountain View, in the county of Santa C ara and State of California, have invented new 'and useful Improvements in Bread-Slicers, of which the following is a specification.

My invention relates to an apparatus for 'slicing bread and like articles which are in the form of loaves.

It consists in the combination of iarts, and yin details of construction which will be more fully explained by reference to the accompanying drawings, in whichigure 1 is a side elevation of my apparatus.

Fie. 4 is a partial detailed plan of the feed roller actuating mechanism. Fig. 5 is an end View showing the cutter, gears, rack and connected parts.

It is the object of my invention to rovide an apparatus by which bread and li e substances may be sliced by the action of a rolling cutter.

As shown in the drawing, A is a base of any suitable character, having sides, ends and uprights for supporting, the various parts o the mechanism, and said structure may be made foldable in such a manner that the funechanism can be inclosed therein when out "inf use. Near one' end of the structure is journaled a shaft 2 upon which is carried a wheel or disk 3, and the shaft and disk may be turnegg-.l -by a crank applied to a square projecting e'd 4 of the shaft, or by other suitable or desired means. Upon the disk is a crank pin 5, with. which one end of a curved Nor pitman 6 is connected; the other end carrying a pivot pin upon which the cutting disk 7 mounted.

8 is a rack bar having the teeth on its lower edge and said rack bar is adjustably supported in slots in posts 9 by screw-bolts and lock nuts 1.0, the posts being vertically slotted so that the bar may be raised or depressed and locked in any desired position,

and this allows the cutting disk and con-v nected operating mcchanlsmto be raised or depressed with relation to the base or l'loor over which the cutter is movable.

11. is a gear-wheel mounted upon the shaft I which is carried in a frame or guide 12, and

below this gear is a pinion 13 which is fixed to the shaft of the cutting disk '7. AThe frame 12 has upon its upper edge a flange or Fig. 2 is a plan View. Fig. 3 is an' elevation partly in section of the feed roller.

rib 14, and this is adapted to travel in a slot in the side of bar S.. Its office is to retain the gear-carrying frame, and maintain the upper gear in mesh with the rack, andthe pinion in mesh with this upper intermediate gear, at the same time allowing the frame or support 12 to be moved backward and forward by the revolutionof the crank-wheel or disk 3, and the resultant reciprocation of the connecting rod or pitman 6 which is connected with the slidable frame 12.

The o eration of this port-ion ofthe appal ratus wil be as follows: When the disk 3 is turned, its revolution acting upon the pitman 6 causes-the guided frame or sup ort 12 to slide with relation to the rack liar which forms its guide as previously described. This motion causes the. gear 11 to revolve, and the motion transmitted from this gear revolves the inion 13 in the opposite direction, and wit it the cutting disk 7, and this revolution of the disk While at the same time traveling over the base upon which the bread is supported, produces an independent revolution of the disk, while it is being reciprocated across the board, and this independent revolution makes a drawing cut which is very elective in severing slices from friable or 1 ou glil material, which is difficult to A ,plate 16, the springs ho ding the plate against the loaf so that the feed mechanism to be hereafter described, will take a firm hold to advance the loaf after eachl stroke of the pitman and corres onding movement of the cutting disk. T is plate 1 6 and the s rings are carried upon a slotted bar 17, whic may be moved out or in to accommodate the character of the loaf to be cut. This bar is secured by a bolt and lock nut as at 18 and it will be seen that it may be thus turned at an angle with the line of travel of the cutter, so that if it is desired to slice the bread in this fashion, the bread will be presented to the cutter at whatever angle rthe support 16 may cause it to take I In order to feed the bread forward I have shown a toothed roller v19 which is j ournaled in such position that the loaf of bread will the loaf of bread, will advance the breadafter each cut has been made. The revolution ci the roller is eiilected by the pinion 2O iixed to the shaft oi the roller below the surface upon which the bread lies, and this pinion is engaged by a rack 2l slidable in the channel corresponding with the position of the pinion. This rack 2l extends to a point contiguous to the crank-Wheel-3, and has connected with it an upwardly extending arm 22 having a vertical slot 23 thi-ou h which a iulcruni pin 24 passes. nUpon t e crank disk 3 are projecting pins 25,:and these pins are so placed with relation .to the bar that the', contact with its upper end as they pass, and thus tilt the bar 22 about its'fulcrumed bolt 2d, ,and4 correspondingly reciprocate the rack. 2i., and thus revolve the feed roller 1Q and advance the bread aft-er' each slice has be in. out. The bar 22 and the rack may be rc .ii-ned by any suitable device. have here shown a spiral spring 26 Which is suffic. it .tor the purpose.

in order to prevent the feed-roller 19 from rotating backwardly upon the return of the movingl parts just described I have show n the pper end ci the roller teeth as having a atchet form as at 27, and a spring-pressed yin engages with these ratchet teeth. f he incline of one side of the ratchet-teeth allows the pin which is carried with the shaft et the pinion 2O to pass over the teeth without moving the roller, the latter being loosely llioin'nalfu upon the vertical shaft 20au of the When the pinion 2O and its shaft pinion 20. are turned inthe opposite direction by the reciprocation of the rack 2l, the pin 2S will engage the substantially vertical edges of the ratchet teeth, and will thus turn the ratchet and the roller l 9, of which it forms a part, and advance' the bread as previously described.

Having thus described my invention, what i claim and desire to secure by Letters Patent is- 1.
